In a blog post, John Luther, the Project Manager of Google's WebM Project, has announced that Skype now supports the VP8 codec. The VP8 support is already available for Windows users who are using Skype 5.5. VP8 will be used to encode and decode the Skype video call if both the caller and receiver have clients that support the codec.

So what, if anything, does this change? I'd assume Skype already has better compression algorithms and is still going to default to them, so I can't see this as a big push for mobile hardware decode. Skype is also a closed ecosystem, so it's not as if it's going to affect any other devs.
